Ferrite offers good saturation over wide temperature range

28 May 2008 Passive Components

L Material from Magnetics is a MnZn power ferrite with a permeability of 900, which is optimised for transformer and inductor applications from 500 kHz to 3 MHz. Within this range, AC core losses are minimised and the loss versus temperature curve exhibits its minimum at a suitable elevated temperature between 70°C and 100°C. In addition, the Curie temperature is over 300°C, so that saturation is good across a wide temperature range.

L Material is a suitable solution for many circuit requirements, especially DC-DC converters and high frequency filters. It is offered in a wide variety of core shapes and sizes up to 30 mm, including planars, PQs, toroids and other shapes. Larger sizes are also available for special applications.
